TCW:"At the beginning, abc company was only a grocery wholesaler. But now is already a large grocery retailers."
Incorrect. You are missing a subject in your second sentence.

Nadia:"At the beginning, abc company was just a grocery wholesaler, but now it is a big grocery retailers."
Incorrect. "Wholesaler" and "retailers" lack parallelism. "Retailers" cannot follow "a."

Teacher:"abc company is a grocery wholesaler at the beginning, now I have became a large grocery retailers."
Incorrect. What does this have to do with "I"? "Have became" is also grammatically wrong.

What I believe is correct:
ABC Company was only a grocery wholesaler in the beginning, but it has since grown into a much larger grocery retailer.

At the beginning when ABC Company is a grocery wholesaler, but is now a large grocery retailers.

ABC company was originally a grocery wholesaler but it is now one of the big grocery retailers.

注意！！！！！！

1.是ABC Company，並不是abc company！！！

所以應該是：

At the beginning of time, ABC Company is a grocery wholesaler, but now is a large grocery retailers.

在開始時候, abc company只是一間 grocery wholesaler, 但現在已是一間大的grocery retailers.

At the beginning, abc company was just a grocery wholesaler, but now it is a big grocery retailers.

在開始時候, abc company只是一間 grocery wholesaler, 但現在已是一間大的
grocery retailers.

At the beginning, abc company was only a grocery wholesaler. But now is
already a large grocery retailers.
